Well, first of all, there are limited numbers of bows that come in your draw length as you've said. Secondly, a real bow shop will have the modules available to set you up for test firing. I know my bow shop does. You live in Texas. There are bow shops in Texas that can help you. Yup, you might have to travel a few extra miles, but it's worth the trip. You seem to have a lot of info I wouldn't expect from a newbie. I take it you've done your research or you're pulling our leg. Either way, a good bow shop can help you out. My bow shop is in Maryland... I live in NY.
